2019-03-11audio: use qapi AudioFormat instead of audfmt_eKővágó, Zoltán
I had to include an enum for audio sampling formats into qapi, but that meant duplicating the audfmt_e enum. This patch replaces audfmt_e and associated values with the qapi generated AudioFormat enum. This patch is mostly a search-and-replace, except for switches where the qapi generated AUDIO_FORMAT_MAX caused problems.

2019-03-11qapi: qapi for audio backendsKővágó, Zoltán
This patch adds structures into qapi to replace the existing configuration structures used by audio backends currently. This qapi will be the base of the -audiodev command line parameter (that replaces the old environment variables based config). This is not a 1:1 translation of the old options, I've tried to make them much more consistent (e.g. almost every backend had an option to specify buffer size, but the name was different for every backend, and some backends required usecs, while some other required frames, samples or bytes). Also tried to reduce the number of abbreviations used by the config keys. Some of the more important changes: * use `in` and `out` instead of `ADC` and `DAC`, as the former is more user friendly imho * moved buffer settings into the global setting area (so it's the same for all backends that support it. Backends that can't change buffer size will simply ignore them). Also using usecs, as it's probably more user friendly than samples or bytes. * try-poll is now an alsa backend specific option (as all other backends currently ignore it) Signed-off-by: Kővágó, Zoltán <DirtY.iCE.hu@gmail.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Message-id: 5461b514dbf3e0bc31b0abb6498a9b3a008c271e.1552083282.git.DirtY.iCE.hu@gmail.com Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2019-03-08qcow2: Don't assume 0 is an invalid cluster offsetKevin Wolf
The cluster allocation code uses 0 as an invalid offset that is used in case of errors or as "offset not yet determined". With external data files, a host cluster offset of 0 becomes valid, though. Define a constant INV_OFFSET (which is not cluster aligned and will therefore never be a valid offset) that can be used for such purposes. This removes the additional host_offset == 0 check that commit ff52aab2df5 introduced; the confusion between an invalid offset and (erroneous) allocation at offset 0 is removed with this change.

2019-03-08iotests: ask QEMU for supported formatsAndrey Shinkevich
Supported formats listed by 'qemu' may differ from those listed by 'qemu-img' due to whitelists. Some test cases require specific formats that may be used with qemu. They can be inquired directly by running 'qemu -drive format=help'. The response takes whitelists into account. The method supported_formats() serves for that. The method decorator skip_if_unsupported() checks if all requested formats are whitelisted. If not, the test case will be skipped. That has been implemented in the 'check' file in the way similar to the 'test notrun' mechanism.

2019-03-08block: iterate_format with account of whitelistingAndrey Shinkevich
bdrv_iterate_format (which is currently only used for printing out the formats supported by the block layer) doesn't take format whitelisting into account. This creates a problem for tests: they enumerate supported formats to decide which tests to enable, but then discover that QEMU doesn't let them actually use some of those formats. To avoid that, exclude formats that are not whitelisted from enumeration, if whitelisting is in use. Since we have separate whitelists for r/w and r/o, take this a parameter to bdrv_iterate_format, and print two lists of supported formats (r/w and r/o) in main qemu.

2019-03-08qcow2: Default to 4KB for the qcow2 cache entry sizeAlberto Garcia
QEMU 2.12 (commit 1221fe6f636754ab5f2c1c87caa77633e9123622) introduced a new setting called l2-cache-entry-size that allows making entries on the qcow2 L2 cache smaller than the cluster size. I have been performing several tests with different cluster and entry sizes and all of them show that reducing the entry size (aka L2 slice) consistently improves I/O performance, notably during random I/O (all tests done with sequential I/O show similar results). This is to be expected because loading and evicting an L2 slice is more expensive the larger the slice is. Here are some numbers on fully populated 40GB qcow2 images. The rightmost column represents the maximum L2 cache size in both cases. Cluster size = 64 KB |-------------+--------------+--------------+--------------| | | 1MB L2 cache | 3MB L2 cache | 5MB L2 cache | |-------------+--------------+--------------+--------------| | 4KB slices | 6545 IOPS | 12045 IOPS | 55680 IOPS | | 16KB slices | 5177 IOPS | 9798 IOPS | 56278 IOPS | | 64KB slices | 2718 IOPS | 5326 IOPS | 57355 IOPS | |-------------+--------------+--------------+--------------| Cluster size = 256 KB |--------------+----------------+--------------+-----------------| | | 512KB L2 cache | 1MB L2 cache | 1280KB L2 cache | |--------------+----------------+--------------+-----------------| | 4KB slices | 8539 IOPS | 21071 IOPS | 55417 IOPS | | 64KB slices | 3598 IOPS | 9772 IOPS | 57687 IOPS | | 256KB slices | 1415 IOPS | 4120 IOPS | 58001 IOPS | |--------------+----------------+--------------+-----------------| As can be seen in the numbers, the only exception to the rule is when the cache is large enough to hold all L2 tables. This is also to be expected because in this case no cache entry is ever evicted so reducing its size doesn't bring any benefit. This patch sets the default L2 cache entry size to 4KB except when the cache is large enough for the whole disk.

2019-03-08iotests: use iotests.VM in 238Stefan Hajnoczi
Test 238 does not require the kvm accelerator. Using the qtest accelerator allows the test to run in both non-kvm and non-tcg environments. iotests.VM implicitly uses the qtest accelerator and is really the class that this test should be using. Switch to that instead of qemu.QEMUMachine. Suggested-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2019-03-08iothread: document about why we need explicit aio_poll()Peter Xu
After consulting Paolo I know why we'd better keep the explicit aio_poll() in iothread_run(). Document it directly into the code so that future readers will know the answer from day one.

2019-03-08iothread: push gcontext earlier in the thread_fnPeter Xu
We were pushing the context until right before running the gmainloop. Now since we have everything unconditionally, we can move this earlier. One benefit is that now it's done even before init_done_sem, so as long as the iothread user calls iothread_create() and completes, we know that the thread stack is ready.

2019-03-08iothread: create the gcontext unconditionallyPeter Xu
In existing code we create the gcontext dynamically at the first access of the gcontext from caller. That can bring some complexity and potential races during using iothread. Since the context itself is not that big a resource, and we won't have millions of iothread, let's simply create the gcontext unconditionally. This will also be a preparation work further to move the thread context push operation earlier than before (now it's only pushed right before we want to start running the gmainloop). Removing the g_once since it's not necessary, while introducing a new run_gcontext boolean to show whether we want to run the gcontext.

2019-03-08iothread: replace init_done_cond with a semaphorePeter Xu
Only sending an init-done message using lock+cond seems an overkill to me. Replacing it with a simpler semaphore. Meanwhile, init the semaphore unconditionally, then we can destroy it unconditionally too in finalize which seems cleaner.
